This invention relates to the use of a group of aryl ureas in treating raf mediated diseases, and pharmaceutical compositions for use in such therapy.

FIELD OF THE INVENTION

[0001] This invention relates to the use of a group of aryl ureas intreating raf mediated diseases, and pharmaceutical compositions for usein such therapy.

BACKGROUND OF THE INVENTION

[0002] The p21^(ras) oncogene is a major contributor to the developmentand progression of human solid cancers and is mutated in 30% of allhuman cancers (Bolton et al. Ann. Rep. Med. Chem. 1994, 29, 165-74; Bos.Cancer Res. 1989, 49, 4682-9). In its normal, unmutated form, the rasprotein is a key element of the signal transduction cascade directed bygrowth factor receptors in almost all tissues (Avruch et al. TrendsBiochem. Sci. 1994, 19, 279-83). Biochemically, ras is a guaninenucleotide binding protein, and cycling between a GTP-bound activatedand a GDP-bound resting form is strictly controlled by ras' endogenousGTPase activity and other regulatory proteins. In the ras mutants incancer cells, the endogenous GTPase activity is alleviated and,therefore, the protein delivers constitutive growth signals todownstream effectors such as the enzyme raf kinase. This leads to thecancerous growth of the cells which carry these mutants (Magnuson et al.Semin. Cancer Biol. 1994, 5, 247-53). It has been shown that inhibitingthe effect of active ras by inhibiting the raf kinase signaling pathwayby administration of deactivating antibodies to raf kinase or byco-expression of dominant negative raf kinase or dominant negative MEK,the substrate of raf kinase, leads to the reversion of transformed cellsto the normal growth phenotype (see: Daum et al. Trends Biochem. Sci.1994, 19, 474-80; Fridman et al. J. Biol. Chem. 1994, 269, 30105-8.Kolch et al. (Nature 1991, 349, 426-28) have further indicated thatinhibition of raf expression by antisense RNA blocks cell proliferationin membrane-associated oncogenes. Similarly, inhibition of raf kinase(by antisense oligodeoxynucleotides) has been correlated in vitro and invivo with inhibition of the growth of a variety of human tumor types(Monia et al., Nat. Med. 1996, 2, 668-75).

SUMMARY OF THE INVENTION

[0003] The present invention provides compounds which are inhibitors ofthe enzyme raf kinase. Since the enzyme is a downstream effector ofp21^(ras), the inhibitors are useful in pharmaceutical compositions forhuman or veterinary use where inhibition of the raf kinase pathway isindicated, e.g., in the treatment of tumors and/or cancerous cell growthmediated by raf kinase. In particular, the compounds are useful in thetreatment of human or animal solid cancers, e.g., murine cancer, sincethe progression of these cancers is dependent upon the ras proteinsignal transduction cascade and therefore susceptible to treatment byinterruption of the cascade, i.e., by inhibiting raf kinase.Accordingly, the compounds of the invention are useful in treatingcancers, including solid cancers, such as, for example, carcinomas(e.g., of the lungs, pancreas, thyroid, bladder or colon), myeloiddisorders (e.g., myeloid leukemia) or adenomas (e.g., villous colonadenoma).

[0004] The present invention therefore provides compounds generallydescribed as aryl ureas, including both aryl and heteroaryl analogues,which inhibit the raf kinase pathway. The invention also provides amethod for treating a raf mediated disease state in humans or mammals.Thus, the invention is directed to compounds which inhibit the enzymeraf kinase and also compounds, compositions and methods for thetreatment of cancerous cell growth mediated by raf kinase wherein acompound of Formula I is administered or pharmaceutically acceptablesalt thereof.

[0026] The invention also relates to compounds per se, of formula I.

[0027] The present invention is also directed to pharmaceuticallyacceptable salts of formula I. Suitable pharmaceutically acceptablesalts are well known to those skilled in the art and include basic saltsof inorganic and organic acids, such as hydrochloric acid, hydrobromicacid, sulfuric acid, phosphoric acid, methanesulphonic acid,trifluoromethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonicacid, 1-naphthalenesulfonic acid, 2-naphthalenesulfonic acid, aceticacid, trifluoroacetic acid, malic acid, tartaric acid, citric acid,lactic acid, oxalic acid, succinic acid, fumaric acid, maleic acid,benzoic acid, salicylic acid, phenylacetic acid, and mandelic acid.

[0028] A number of the compounds of Formula I possess asymmetric carbonsand can therefor exist in racemic and optically active forms. Methods ofseparation of enantiomeric and diastereomeric mixtures are well known toone skilled in the art. The present invention encompasses any isolatedracemic or optically active form of compounds described in Formula Iwhich possess raf inhibitory activity.

General Preparative Methods

[0029] The compounds of Formula I may be prepared by the use of knownchemical reactions and procedures, some from starting materials whichare commercially available. Nevertheless, general preparative methodsare provided below to aid one skilled in the art in synthesizing thesecompounds, with more detailed examples being provided in theExperimental section which follows.

[0030] Substituted anilines may be generated using standard methods(March. Advanced Organic Chemistry, 3^(rd) Ed.; John Wiley: New York(1985). Larock. Comprehensive Organic Transformations; VCH Publishers:New York (1989)). As shown in Scheme 1, aryl amines are commonlysynthesized by reduction of nitroaryls using a metal catalyst, such asNi, Pd, or Pt, and H₂ or a hydride transfer agent, such as fortnate,cyclohexadiene, or a borohydride (Rylander. Hydrogenation Methods;Academic Press: London, UK (1985)). Nitroaryls may also be directlyreduced using a strong hydride source, such as LiAUl (Seyden-Penne.Reductions by the Alumino- and Borohydrides in Organic Synthesis; VCHPublishers: New York (1991)), or using a zero valent metal, such as Fe,Sn or Ca, often in acidic media. Many methods exist for the synthesis ofnitroaryls (March. Advanced Organic Chemistry, 3^(rd) Ed.; John Wiley:New York (1985). Larock. Comprehensive Organic Transformations; VCHPublishers: New York (1989)).

[0031] Nitroaryls are commonly formed by electrophilic aromaticnitration using HO₃, or an alternative NO₂ ⁺ source. Nitroaryls may befurther elaborated prior to reduction. Thus, nitroaryls substituted with

[0032] potential leaving groups (e.g. F, Cl, Br, etc.) may undergosubstitution reactions on treatment with nucleophiles, such as thiolate(exemplified in Scheme II) or phenoxide. Nitroaryls may also underaoUllman-type coupling reactions (Scheme II).

[0033] Nitroaryls may also undergo transition metal mediated crosscoupling reactions. For example, nitroaryl electrophiles, such asnitroaryl bromides, iodides or triflates, undergo palladium mediatedcross coupling reactions with aryl nucleophiles, such as arylboronicacids (Suzuki reactions, exemplified below), aryltins (Stille reactions)or arylzincs (Negishi reaction) to afford the biaryl (5).

[0034] Either nitroaryls or anilines may be converted into thecorresponding arenesulfonyl chloride (7) on treatment withchlorosulfonic acid. Reaction of the sulfonyl chloride with a fluoridesource, such as KF then affords sulfonyl fluoride (8). Reaction ofsulfonyl fluoride 8 with trimethylsilyl trifluoromethane in the presenceof a fluoride source, such as tris(dimethylamino)sulfoniumdifluorotrimethylsiliconate (TASF) leads to the correspondingtrifluoromethylsulfone (9). Alternatively, sulfonyl chloride 7 may bereduced to the arenethiol (10), for example with zinc amalgum. Reactionof thiol 10 with CHClF₂ in the presence of base gives the difluoromethylmercaptam (11), which may be oxidized to the sulfone (12) with any of avariety of oxidants, including CrO₃-acetic anhydride (Sedova et al. Zh.Org. Khim. 1970, 6, (568).

[0035] As shown in Scheme IV, non-symmetrical urea formation may involvereaction of an aryl isocyanate (14) with an aryl amine (13). Theheteroaryl isocyanate may be synthesized from a heteroaryl amine bytreatment with phosgene or a phosgene equivalent, such astrichloromethyl chloroformate (diphosgene), bis(trichloromethyl)carbonate (triphosgene), or N,N′-carbonyldiimidazole (CDI). Theisocyanate may also be derived from a heterocyclic carboxylic acidderivative, such as an ester, an acid halide or an anhydride by aCurtius-type rearrangement. Thus, reaction of acid derivative 16 with anazide source, followed by rearrangement affords the isocyanate. Thecorresponding carboxylic acid (17) may also be subjected to Curtius-typerearrangements using diphenylphosphoryl azide (DPPA) or a similarreagent.

[0036] Finally, ureas may be further manipulated using methods familiarto those skilled in the art.

[0037] The invention also includes pharmaceutical compositions includinga compound of Formula I, and a physiologically acceptable carrier.

[0038] The compounds may be administered orally, topically,parenterally, by inhalation or spray or rectally in dosage unitformulations. The term ‘administration by injection’ includesintravenous, intramuscular, subcutaneous and parenteral injections, aswell as use of infusion techniques. One or more compounds may be presentin association with one or more non-toxic pharmaceutically acceptablecarriers and if desired other active ingredients.

[0039] Compositions intended for oral use may be prepared according toany suitable method known to the art for the manufacture ofpharmaceutical compositions. Such compositions may contain one or moreagents selected from the group consisting of diluents, sweeteningagents, flavoring agents, coloring agents and preserving agents in orderto provide palatable preparations. Tablets contain the active ingredientin admixture with non-toxic pharmaceutically acceptable excipients whichare suitable for the manufacture of tablets. These excipients may be,for example, inert diluents, such as calcium carbonate, sodiumcarbonate, lactose, calcium phosphate or sodium phosphate; granulatingand disintegrating agents, for example, corn starch, or alginic acid;and binding agents, for example magnesium stearate, stearic acid ortalc. The tablets may be uncoated or they may be coated by knowntechniques to delay disintegration and adsorption in thegastrointestinal tract and thereby provide a sustained action over alonger period. For example, a time delay material such as glycerylmonostearate or glyceryl distearate may be employed. These compounds mayalso be prepared in solid, rapidly released form.

[0040] Formulations for oral use may also be presented as hard gelatincapsules wherein the active ingredient is mixed with an inert soliddiluent, for example, calcium carbonate, calcium phosphate or kaolin, oras soft gelatin capsules wherein the active ingredient is mixed withwater or an oil medium, for example peanut oil, liquid paraffin or oliveoil.

[0041] Aqueous suspensions contain the active materials in admixturewith excipients suitable for the manufacture of aqueous suspensions.Such excipients are suspending agents, for example sodiumcarboxymethylcellulose, methylcellulose, hydroxypropyl methylcellulose,sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia;dispersing or wetting agents may be a naturally occurring phosphatide,for example, lecithin, or condensation products or an alkylene oxidewith fatty acids, for example polyoxyethylene stearate, or condensationproducts of ethylene oxide with long chain aliphatic alcohols, forexample heptadecaethylene oxycetanol, or condensation products ofethylene oxide with partial esters derived from fatty acids and hexitolsuch as polyoxyethylene sorbitol monooleate, or condensation products ofethylene oxide with partial esters derived from fatty acids and hexitolanhydrides, for example polyethylene sorbitan monooleate. The aqueoussuspensions may also contain one or more preservatives, for exampleethyl, or n-propyl p-hydroxybenzoate, one or more coloring agents, oneor more flavoring agents, and one or more sweetening agents, such assucrose or saccharin.

[0042] Dispersible powders and granules suitable for preparation of anaqueous suspension by the addition of water provide the activeingredient in admixture with a dispersing or wetting agent, suspendingagent and one or more preservatives. Suitable dispersing or wettingagents and suspending agents are exemplified by those already mentionedabove. Additional excipients, for example, sweetening, flavoring andcoloring agents, may also be present.

[0043] The compounds may also be in the form of non-aqueous liquidformulations, e.g., oily suspensions which may be formulated bysuspending the active ingredients in a vegetable oil, for examplearachis oil, olive oil, sesame oil or peanut oil, or in a mineral oilsuch as liquid paraffin. The oily suspensions may contain a thickeningagent, for example beeswax, hard paraffin or cetyl alcohol. Sweeteningagents such as those set forth above, and flavoring agents may be addedto provide palatable oral preparations. These compositions may bepreserved by the addition of an anti-oxidant such as ascorbic acid.

[0044] Pharmaceutical compositions of the invention may also be in theform of oil-in-water emulsions. The oily phase may be a vegetable oil,for example olive oil or arachis oil, or a mineral oil, for exampleliquid paraffin or mixtures of these. Suitable emulsifying agents may benaturally-occurring gums, for example gum acacia or gum tragacanth,naturally-occurring phosphatides, for example soy bean, lecithin, andesters or partial esters derived from fatty acids and hexitolanhydrides, for example sorbitan monooleate, and condensation productsof the said partial esters with ethylene oxide, for examplepolyoxyethylene sorbitan monooleate. The emulsions may also containsweetening and flavoring agents.

[0045] Syrups and elixirs may be formulated with sweetening agents, forexample glycerol, propylene glycol, sorbitol or sucrose. Suchformulations may also contain a demulcent, a preservative and flavoringand coloring agents.

[0046] The compounds may also be administered in the form ofsuppositories for rectal administration of the drug. These compositionscan be prepared by mixing the drug with a suitable non-irritatingexcipient which is solid at ordinary temperatures but liquid at therectal temperature and will therefore melt in the rectum to release thedrug. Such materials include cocoa butter and polyethylene glycols.

BIOLOGICAL EXAMPLES

[0336] In vitro Raf Kinase Assay:

[0337] In an in vitro kinase assay, raf was incubated with MEK in 20 mMTris-HCl, pH 8.2 containing 2 mM 2-mercaptoethanol and 100 mM NaCl. Thisprotein solution (20 μL) was mixed with water (5 μL) or with compoundsdiluted with distilled water from 10 mM stock solutions of compoundsdissolved in DMSO. The kinase reaction was initiated by adding 25 μL[λ-³³P]ATP (1000-3000 dpm/pmol) in 80 mM Tris-HCl, pH 7.5, 120 mM NaCl,1.6 mM DTT, 16 mM MgCl₂. The reaction mixtures were incubated at 32° C.,usually for 22 min. Incorporation of ³³P into protein was assayed byharvesting the reaction onto phosphocellulose mats, washing away freecounts with a 1% phosphoric acid solution and quantitatingphosphorylation by liquid scintillation counting. For high throughputscreening, 10 μM ATP and 0.4 μM MEK was used. In some experiments, thekinase reaction was stopped by adding an equal amount of Laemmli samplebuffer. Samples were boiled 3 min and the proteins resolved byelectrophoresis on 7.5% Laemmli gels. Gels were fixed, dried and exposedto an imaging plate (Fuji). Phosphorylation was analyzed using a FujixBio-Imaging Analyzer System.

[0338] All compounds exemplified displayed IC₅₀s of between 1 nM and 10μM.

[0339] Cellular Assay:

[0340] For in vitro growth assay, human tumor cell lines, including butnot limited to HCT116 and DLD-1, containing mutated K-ras genes wereused in standard proliferation assays for anchorage dependent growth onplastic or anchorage independent growth in soft agar. Human tumor celllines were obtained from ATCC (Rockville Md.) and maintained in RPMIwith 10% heat inactivated fetal bovine serum and 200 mM glutamine. Cellculture media and additives were obtained from Gibco/BRL (Gaithersburg,Md.) except for fetal bovine serum (JRH Biosciences, Lenexa, Kans.). Ina standard proliferation assay for anchorage dependent growth, 3×10³cells were seeded into 96-well tissue culture plates and allowed toattach overnight at 37° C. in a 5% CO₂ incubator. Compounds weretitrated in media in dilution series and added to 96-well cell cultures.Cells were allowed to grow 5 days typically with a feeding of freshcompound containing media on day three. Proliferation was monitored bymeasuring metabolic activity with standard XTT calorimetric assay(Boehringer Mannheim) measured by standard ELISA plate reader at OD490/560, or by measuring ³H-thymidine incorporation into DNA followingan 8 h culture with 1 μCu ³H-thymidine, harvesting the cells onto glassfiber mats using a cell harvester and measuring ³H-thymidineincorporation by liquid scintillant counting.

[0341] For anchorage independent cell growth, cells were plated at 1×10³to 3×10³ in 0.4% Seaplaque agarose in RPMI complete media, overlaying abottom layer containing only 0.64% agar in RPMI complete media in24-well tissue culture plates. Complete media plus dilution series ofcompounds were added to wells and incubated at 37° C. in a 5% CO₂incubator for 10-14 days with repeated feedings of fresh mediacontaining compound at 3-4 day intervals. Colony formation was monitoredand total cell mass, average colony size and number of colonies werequantitated using image capture technology and image analysis software(Image Pro Plus, media Cybernetics).

[0342] In vivo Assay:

[0343] An in vivo assay of the inhibitory effect of the compounds ontumors (e.g., solid cancers) mediated by raf kinase can be performed asfollows:

[0344] CDI nu/nu mice (6-8 weeks old) are injected subcutaneously intothe flank at 1×10⁶ cells with human colon adenocarcinoma cell line. Themice are dosed i.p., i.v. or p.o. at 10, 30, 100, or 300 mg/Kg beginningon approximately day 10, when tumor size is between 50-100 mg. Animalsare dosed for 14 consecutive days once a day; tumor size was monitoredwith calipers twice a week.

[0345] The inhibitory effect of the compounds on raf kinase andtherefore on tumors (e.g., solid cancers) mediated by raf kinase canfurther be demonstrated in vivo according to the technique of Monia etal. (Nat. Med. 1996, 2, 668-75).
